Casey Winters Portfolio
Built and scaled Grubhub's marketing team (3 cities to 1,000+, a $1M Series A to a $7.3B exit), then led Pinterest's growth product team, turning SEO into a scalable acquisition channel and increasing signup/mobile conversion 5x while Pinterest grew from 40 million to over 500 million active users.
What makes it work
A breakdown of the choices that make this portfolio stand out.
Before-and-after figures paired with the specific lever used
Grubhub's 3-cities-to-1,000+ and Pinterest's 40M-to-500M+ growth are each tied to a named mechanism (demand-side acquisition, SEO-driven signups), not just a bare outcome.
An exact conversion multiplier
A stated "5x increase" in signup/mobile conversion is a specific, falsifiable claim rather than "significantly improved conversion."
A trajectory from tactical execution to executive ownership
Moving from founding a marketing team to leading growth product to CPO shows marketing skill compounding into broader leadership scope.
What Marketing Managers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
State the starting condition and the ending condition together (3 cities to 1,000+) — a bare percentage or "grew significantly" claim is far less convincing.
Name the specific channel or lever that drove a result (SEO, demand-side acquisition) rather than describing growth in the abstract.
If your career moved from a marketing-specific role into broader product or executive ownership, say so plainly — it shows marketing skill compounding into leadership scope.
